Fluid interaction device, fluid interaction arrangement and method for producing same

A fluid interaction arrangement, comprising:

• a fluid supply element having a tube reception portion;
• and
• a fluid interaction device for establishing an interaction with a fluid, the fluid interaction device having a housing member which accommodates a fluid interaction portion, the fluid interaction portion being adapted to interact with a fluid within the housing member, wherein the housing member further comprises an electrical contact portion with a socket for receiving an electrical plug and a connection portion which is formed as a weldable, tubular end portion, wherein the housing member includes an injection molded thermoplastic material, wherein the housing member is connected to a joining portion of the fluid supply element by means of a welded joint, wherein the tubular end portion is rotationally symmetric along a joining axis, wherein the joining portion comprises an annular groove, wherein the welded joint is a friction welded joint formed between at least one circumferential surface of the tubular end portion and at least one circumferential surface of the tube reception portion such that a fluid-tight connection is established at the friction welded joint, and wherein the fluid interaction portion includes at least one of a sensor arrangement for sensing a state variable of fluid, a damper arrangement, or an active interaction portion, wherein the active interaction portion is a fluid cooler and/or a fluid heater.
